    firefox vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 11.10
    - Ubuntu 11.04
    - Ubuntu 10.10
    - Ubuntu 10.04 LTS
    
    Summary:
    
    Several security issues were fixed in Firefox.
    
    Software Description:
    - firefox: Mozilla Open Source web browser
    
    Details:
    
    Soroush Dalili discovered that Firefox did not adequately protect against
    dropping JavaScript links onto a frame. A remote attacker could, through
    cross-site scripting (XSS), exploit this to modify the contents or steal
    confidential data. (CVE-2012-0455)
    
    Atte Kettunen discovered a use-after-free vulnerability in Firefox's
    handling of SVG animations. An attacker could potentially exploit this to
    execute arbitrary code with the privileges of the user invoking Firefox.
    (CVE-2012-0457)
    
    Atte Kettunen discovered an out of bounds read vulnerability in Firefox's
    handling of SVG Filters. An attacker could potentially exploit this to make
    data from the user's memory accessible to the page content. (CVE-2012-0456)
    
    Mike Brooks discovered that using carriage return line feed (CRLF)
    injection, one could introduce a new Content Security Policy (CSP) rule
    which allows for cross-site scripting (XSS) on sites with a separate header
    injection vulnerability. With cross-site scripting vulnerabilities, if a
    user were tricked into viewing a specially crafted page, a remote attacker
    could exploit this to modify the contents, or steal confidential data,
    within the same domain. (CVE-2012-0451)
    
    Mariusz Mlynski discovered that the Home button accepted JavaScript links
    to set the browser Home page. An attacker could use this vulnerability to
    get the script URL loaded in the privileged about:sessionrestore context.
    (CVE-2012-0458)
    
    Daniel Glazman discovered that the Cascading Style Sheets (CSS)
    implementation is vulnerable to crashing due to modification of a keyframe
    followed by access to the cssText of the keyframe. If the user were tricked
    into opening a specially crafted web page, an attacker could exploit this
    to cause a denial of service via application crash, or potentially execute
    code with the privileges of the user invoking Firefox. (CVE-2012-0459)
    
    Matt Brubeck discovered that Firefox did not properly restrict access to
    the window.fullScreen object. If the user were tricked into opening a
    specially crafted web page, an attacker could potentially use this
    vulnerability to spoof the user interface. (CVE-2012-0460)
    
    Bob Clary, Christian Holler, Jesse Ruderman, Nils, Michael Bebenita,
    Dindog, David Anderson, Jeff Walden, Vincenzo Iozzo, and Willem Pinckaers
    discovered memory safety issues affecting Firefox. If the user were tricked
    into opening a specially crafted page, an attacker could exploit these to
    cause a denial of service via application crash, or potentially execute
    code with the privileges of the user invoking Firefox. (CVE-2012-0461,
    CVE-2012-0462, CVE-2012-0464)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 11.10:
      firefox                         11.0+build1-0ubuntu0.11.10.1
    
    Ubuntu 11.04:
      firefox                         11.0+build1-0ubuntu0.11.04.1
    
    Ubuntu 10.10:
      firefox                         11.0+build1-0ubuntu0.10.10.2
    
    Ubuntu 10.04 LTS:
      firefox                         11.0+build1-0ubuntu0.10.04.2
    
    After a standard system update you need to restart Firefox to make
    all the necessary changes.
